We're dividing 65889900 by 845 
The aim is to understand the frequency of 845 in 65889900.

Moving on to step 1:
The number 845 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 845

Advancing to step 2:
If we divide 65 by 845, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 845

Advancing to step 3:
The number 845 fits into 658 0 times, leaving a remainder of 658.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 658 to get 658.
Fetch the next digit (8) from the dividend, attach it to 658 and continue: 6588 / 845

Let's proceed to step 4:
If we divide 6588 by 845, we get 7 and a remainder of 673.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5915 from 6588 and we're left with 673.
Take the next digit (9) from the dividend and append it to 673, then repeat: 6739 / 845

Moving on to step 5:
When dividing 6739 by 845, we get 7 with a remainder of 824.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtract 5915 from 6739 to get 824.
Fetch the next digit (9) from the dividend, attach it to 824 and continue: 8249 / 845

Let's proceed to step 6:
845 can be fit into 8249 9 times, resulting in a remainder of 644.
Write down 9 as next digit of the result. 
Result so far: 779.0
Deduct 7605 from 8249 and we're left with 644.
Grab the next digit (0) from the dividend, add it to 644, then carry on: 6440 / 845

Moving on to step 7:
845 can be fit into 6440 7 times, resulting in a remainder of 525.
Put 7 as the next digit of the answer. 
Result so far: 7797.0
Deduct 5915 from 6440 and we're left with 525.
Bring next digit (0) of the dividend behind the 525 and repeat the process: 5250 / 845

Let's proceed to step 8:
The number 845 fits into 5250 6 times, leaving a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 77976.0
Deduct 5070 from 5250 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 9:
When dividing 1800 by 845, we get 2 with a remainder of 110.
The number 2 becomes the next digit in our result. 
Result so far: 77976.2
Deduct 1690 from 1800 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
The number 845 fits into 1100 1 times, leaving a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 77976.21
Subtract 845 from 1100 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 11:
The number 845 fits into 2550 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 77976.213
Subtracting 2535 from 2550 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
If we divide 150 by 845, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 77976.213
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
1500 divided by 845 is 1 with a remainder of 655.
Use 1 as the next digit of our solution. 
Result so far: 77976.21301
If we subtract 845 from 1500, we get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 14:
845 goes into 6550 7 times with a remainder of 635.
Record the quotient 7 as the next digit in the result. 
Result so far: 77976.213017
If we subtract 5915 from 6550, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 15:
When dividing 6350 by 845, we get 7 with a remainder of 435.
The next digit of our result is 7. 
Result so far: 77976.2130177
Deduct 5915 from 6350 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

The quotient of the division is 77976.2130177, and the remainder is 4.35e-06.
